For instructions, I'll note a few things. As of 2007, we know our main sprite is the well-known mascot of Scratch: Scratch-Cat, who is labelled as Sprite1. And as you see inside, you can open the other sprite I added that is ''Sprite2'' to see a repeating sequence of the definitions of the custom blocks that should be in Scratch but still reside in PenguinMod and blocks that belong to me but can be used by you as well! I hope you have fun with these blocks!
Ignore the running Sprite1. Please. If you want it then sure, have it.
